Very Good, One Gigantic Flaw
Slack was super easy to set up and get started with. The format and features were exactly what my team needs right now and in some cases have been begging for for a while now.
BUT... There is one fatal flaw that will prevent my entire enterprise from adopting it. Where is the end to end encryption? It cannot possibly be ok in this day and age for that feature to be missing. The current security policy for Slack is little better than a statement saying "Trust us, we promise not to compromise your data."
